The movie comes out on November 19. But in the meanwhile, there's a lot to unpack from this trailer. It's filled with areas and magical animals we've never seen before.

Rowling published a book with the same name in 2001, "written" by Newt Scamander, the main character in the movie. The book goes through all the magical beasts that Scamander encountered on his travels and catalogs them. I've consulted it to try to identify all the magical animals in the trailer, but there are still some mysteries.

Here's a complete breakdown of the trailer. Check it out:

1/

Before the footage starts rolling, we get a black screen and some voiceover. It sounds like a witness's account of a supernatural event. "It was like, um, like a ghost!" The footage starts with Percival Graves, an American auror, entering a house. It looks like he's going in to inspect something.

2/

The camera pans out, and the building turns out to be in ruins. The voiceover continues, "I saw its eyes, shining white eyes! And it dove down underground." The description doesn't match anything in the book version of "Fantastic Beasts and Where to Find Them," which is Newt Scamander's catalogue of magical beasts he's aware of.

Warner Bros.

3/

We see the witness, dressed in a gray coat. Then there's a boom. He looks up and the walls are cracking. Already, it feels like we're dropped in the middle of a supernatural mystery.

Warner Bros.

4/

Something underground runs away, tearing up the street. There's a magical beast that escaped. We know that Graves is tasked with tracking down Newt Scamander, the main character of "Fantastic Beasts." Is he responsible for an escaped magical creature?

Warner Bros.

5/

Now we see Eddie Redmayne, our Newt Scamander. It looks like he's arriving in New York City on a boat, looking at the skyline.

Warner Bros.

6/

We see the entrance of the Woolworth Building in downtown Manhattan. It's the home of the Magical Congress of the United States of America (MACUSA), which is the governing body of the American wizarding world.

Warner Bros.

7/

The trailer takes us into MACUSA, where we see a woman racing up the stairs and across MACUSA's seal. It looks like it's Porpetina Goldstein, who we know is a "down to earth" witch working at the ministry, because she looks like she could be Katherine Waterson and she's dressed business casual.

Warner Bros.

8/

An offscreen person's hand passes a wand to an old elf, and it magically floats toward him. The elf is sitting by this fluffy, wheel-based contraption. Maybe it's for wand cleaning? Regardless, this elf is the first magical creature we've seen.

Warner Bros.

9/

It looks like we're in a council meeting presided by Seraphina Picquery, MACUSA's president. The crowd is interesting — it's a diverse set of people, which you can tell based on the costumes and hats everyone is wearing. Everyone's standing and the room is pretty dark, which makes it seem like a serious discussion is about to take place.

Also, instead of the MACUSA seal on the floor, there's a pentagram painted gold with darker gold circles in each one. The triangle of the pentagram facing Picquery is a different shade of gold, but she's covering most of it, so you can't tell what else is there.

It's too dark to tell what's through the door on the far end of the room. It could just be a hallway, or it could be something else.

10/

Here, the trailer engages in some editing trickery. We see Graves in the same room, leaning forward as if he's trying to make eye contact with the person in front of the room.

11/

And then we see Picquery looking to her left, as if she's connecting with his eye contact on the left side of the room.

Warner Bros.

12/

But if you look back to the first shot of the room, Graves isn't there. So it must be from a different scene. It also tells us that tracking down Newt Scamander must be a high-priority task for MACUSA, if the auror in charge of it is present in the room where congress is meeting.

Warner Bros.

13/

Now the trailer launches into a series of magical scenes. We see Porpentina Goldstein knocking on some kind of mirror that makes her look like a cartoon...

...and some extremely 1940s-looking guys playing cards with magic.

"Yesterday, a wizard entered New York with a case..." Goldstein says in the voiceover. We see Scamander swaggering through customs, holding his magical case.

Warner Bros.

16/

"...a case full of magical creatures..."

Jacob Shamsian/INSIDER

17/

"...and, unfortunately, some have escaped," the voiceover finishes. We see Jacob Kowalski, a no-maj (that is to say, muggle) peering at a banging suitcase with a latch that just opened. What's inside? And who's in the picture on the wall?

Warner Bros.

18/

We hear a piglike squeal and an animal leaps out at Jacob's face! It's pink, pig-sized, and looks like it has a mop of pink hair on top of it.

Warner Bros.

Looking in the book "Fantastic Beasts and Where to Find Them," it's probably a Nogtail. They're somewhat dangerous creatures that "resemble stunted piglets with long legs, thick, stubby tails, and narrow black eyes."

To jump with the force that this animal jumped, it makes sense that it'd have long legs. The book also says that they're "exceptionally fast and difficult to catch."

Furthermore, "The longer the Nogtail is left undetected and the bigger it grows, the longer the blight on the farm into which it has entered." If it escapes, that makes it a sort of ticking time bomb for the plot, becoming more dangerous with every passing day it isn't caught.

19/

Scamander and Kowalski enter the home of Porpentina and her sister, Queenie. "This is Mr. Scamander," Porpetina says. "He's lost something I'm going to help him find.

Warner Bros.

20/

Newt's skating across the ice, but there's something glowing moving underneath. There's nothing in the book that tells us what this could be.

Warner Bros.

21/

Porpetina looks up, and she sees a big buglike creature. It looks like a billywig!

Warner Bros.

In "Fantastic Beasts," J.K. Rowling says that billywigs are "half an inch long." This creature looks bigger than that, but all the other descriptors fit. It's "a vivid sapphire blue." Furthermore, its "wings are attached to the top of its head and are rotated very fast so that it spins as it flies. At the bottom of the body is a long thin sting." That fits. If you get stung by one, you feel giddy and then start levitating.

22/

We see a dark slithering creature coiled up, with a beak pointing at us. Is it a dragon? Or maybe it's an Occamy, "A plumed, two-legged winged creature with a serpentine body" which reaches up to 15 feet in length.

Warner Bros.

23/

Oh cool, some fashionable elves. They look liberated, unlike the house elves we know from European wizardry.

Warner Bros.

24/

A chandelier erupts at an event in honor of Henry Shaw, a United States senator. Did a magical beast break loose here?

Warner Bros.

25/

Yup, the senator's dad is played by Jon Voight.

Warner Bros.

26/

Picquery says they have to contain the escaped beasts before no-majes get too freaked out. She has a map of Manhattan with a glowing line snaking through the streets. Maybe it's a way of tracking magical beasts.

Warner Bros.

27/

Scamander gives Kowalski a helmet. They're about to do something dangerous. It looks like it's from the same scene as the wintery shot we saw earlier, over the ice.

Warner Bros.

28/

A Thunderbird emerges from the ground and soars into the air. It might be the same creature that tunneled underground at the beginning of the trailer.

Next, we see Swooping Evil, a birdlike creature in Scamander's care. But what's going on here? What's this concrete room? Why are there two people collapsed on the ground? Why is someone stuck in what looks like a tar pit?

Jacob Shamsian/INSIDER

30/

Now it looks like Scamander and Graves might be dueling, or teaming up to try to take down a creature we don't see onscreen.

Warner Bros.

31/

This sloth dude is carrying something and galloping along. It might be a Demiguise.

Warner Bros.

According to the book "Fantastic Beasts," "The Demiguise is a peaceful herbivorous beast, something like a graceful ape in appearance, with large, black, doleful eyes more often than not hidden by its hair. The whole body is covered with long, fine, silky, silvery hair. Demiguise pelts are highly valued as the hair may be spun into Invisibility Cloaks." I think it looks more like a sloth than an ape, but all the other descriptors fit.

32/

Some crazy, roaring black cloud thing erupts from Times Square and attacks the city.

Warner Bros.

33/

Could it be a lethifold?

Warner Bros.

It's not really clear what this is. It might be a lethifold, which "resembles a black cloak perhaps half an inch thick" and "glides around the ground at night." It kind of envelops victims and get bigger with the more victims it consumes. The book makes them seem like especially dangerous dementors. This could be an enormous lethifold, but it isn't so much gliding as it is whirling around like a tornado.

34/

Scamander and Kowalski clap for us. It's a great trailer! "I want to be a wizard," Kowalski says. Me, too.
